AirLife®nCPAP Operator’s Manual 1

Product Description
The AirLife®nCPAP System Driver is intended to provide continuous
positive airway pressure (CPAP) for use in hospitals to treat spontaneously
breathing newborns and infants with Respiratory Distress Syndrome (RDS),
or are recovering from RDS under the supervision of qualified personnel
(e.g., respiratory therapist or nurse). The driver operates on hospital or tank
air, and oxygen. The device has an internal battery and can be used for
intra-hospital transport, but is not intended for use in ambulances or aircraft.
The AirLife®nCPAP System Driver incorporates an electronic blender using
solenoid valves and servo controlled flow to maintain a user-set pressure
and FiO2. The system also utilizes a long-life oxygen sensor. The user
interface displays oxygen concentration, CPAP level, flow rate, trending, and
power and alarm conditions. The oxygen sensor automatically calibrates
every time the instrument is powered on. The driver is part of a larger
system that includes an nCPAP generator, fixation device, and patient
interface (prongs and/or masks).

Product Specification
Gas Supply
41–66 psig (nominal 50 psig) clean, dry, medical air and oxygen. External
pressure regulators should be used if source pressures exceed 66 psig.
Pressure Control / Monitoring
Control Range: 2–10 cmH2O
Monitor Range: 1–11 cmH2O, accuracy ±1 cmH2O. Pressure is displayed as
<1 or >11 when outside this range.
Oxygen Control / Monitor
Control/Display Range: 21%–100% O2, accuracy ±3 percentage points
Monitor Range: 17%–104%O2, accuracy ±3 percentage points
Sensor Type: Long Life Ultrasonic (5+ years)
Flow Monitoring
Range: 0–15 LPM, accuracy ±10%
Power Supply
15 V DC, 3.3 A from included AC adapter (GlobTek, Inc. Model number
GTM21097-5015) or an internal 12 V sealed lead/acid battery. The battery
has a life of four (4) hours from a full charge (up to 16 hours required for
recharge).
Weight
Approx. 15 pounds
Dimensions
8 ½ x 8 ½ x 6 ½ inches (excluding gas inlets, patient outlets, and mounting
brackets)
Pressure Relief (2 systems)
Automatic electronic valve system preset to vent to ambient air when a High
Pressure alarm occurs
Mechanical internal relief valve preset to vent at 3 ±0.15 psig (211 ±11
cmH2O)
Flow Limit
Electronic flow limit to prevent the delivery flow from exceeding 3 LPM over
Target Flow or 15 LPM.
Alarm System
Alarms are delayed for 120 seconds after entering the main screen in order
to allow time for patient setup. If the patient setup takes longer than 120
seconds, the alarms can be muted for an additional 120 seconds by
pressing the alarm mute/reset button or the system can be placed into
Standby Mode.
AirLife®nCPAP Operator’s Manual 3

Supply Gas Pressure Alarm: An audible and visual Source Pressure
alarm will activate if the inlet pressure of one, or both, of the gas sources are
outside of the specified gas supply range. There is a 1 second delay for this
alarm. The alarm message will indicate the specific gas source that is out of
specification. If a single gas source goes out of range during operation, then
only the remaining gas source will be available (air or oxygen) and FiO2
blending will become inoperable. The user will be able to select either ‘Air
Only’ or ‘Oxygen Only’ to allow the unit to operate in single-gas source mode
and mute the FiO2alarms while the problem is corrected. The system will
automatically return to normal operation (blending to the original FiO2
setting) when the problem is corrected and the source pressures are
returned to within the specified range.
High Pressure Alarm: An audible and visual High Pressure alarm has dual
limits. The first limit will activate the alarm when the monitored pressure is
greater than or equal to 12 cmH2O for 2 seconds. The second limit will
activate the alarm immediately when the monitored pressure is greater than
or equal to 18 cmH2O. This alarm automatically activates the electronic
pressure relief solenoid and closes the patient delivery solenoid, which
instantly reduces the pressure in the patient circuit to zero. Approximately
every three (3) seconds, the system will reinstate flow. If the alarm condition
has cleared, the unit will operate normally. If the alarm condition still exists,
the ‘High Pressure’ alarm will cycle through the 3-second loop.
Elevated Pressure Alarm: An audible and visual Elevated Pressure alarm
is preset for a CPAP pressure that is 2 cmH2O above the Set CPAP level.
There is a 5 second delay for this alarm
Low Pressure Alarm: An audible and visual Low Pressure alarm is preset
for a CPAP pressure that is 2 cmH2O below the Set CPAP level. There is a
14 second delay for this alarm.

Disconnect Alarm: An audible and visual ‘Disconnect’ alarm is preset to
detect a pressure line or patient interface that has come loose or that is
disconnected. The alarm is set to activate according to the following list:
Flow (LPM) CPAP (cmH2O)
≥0 ≤1
≥6 ≤2
≥9 ≤3
≥12 ≤4
≥14 ≤5
While the alarm is active, the patient flow will remain within ±2 LPM of Target
Flow. There is a 5 second delay for this alarm.
Leak Alarm: An audible and visual Leak alarm is preset for a flow rate that
is 3 LPM above the Target Flow rate or for a flow that is greater than 15
LPM. There is a 5 second delay for this alarm
Low Flow Alarm: An audible and visual Low Flow alarm is preset for flow
rates at or below 3 LPM. There is a 10 second delay for this alarm.
Oxygen Concentration Alarms: The oxygen concentration is allowed to
operate within a ±3 %O2range without alarming.
A Medium Priority warning will activate whenever the product of the variance
outside of the FiO2range and the duration (in seconds) of the variance
exceeds 20.
A High Priority alarm will activate whenever the product of the variance
outside of the FiO2range and the duration (in seconds) of the variance
exceeds 30.
For example: if the Set %O2is 30% and the reading is 35% for a period of
ten (10) seconds, a Medium Priority warning will activate. In this case the
reading is 2 percentage points outside of the ±3 percentage point range. If
the Set %O2is 30% and the reading is 35% for a period of 15 seconds, a
High Priority alarm will activate.
Battery Alarms: An audible and visual Low Battery alarm has dual limits.
The first limit will activate the medium priority alarm when the battery falls
below 10% remaining (approx. 24 minutes). The second limit will activate
the high priority alarm when the battery falls below 5% remaining (approx. 12
minutes). There is a 2 second delay for this alarm. An audible and visual
Charge Fault alarm will indicate if the battery is not charging properly. The
system verifies proper charging at start up and during the routine oxygen
calibration. There is a 5 second delay for this alarm.
AirLife®nCPAP Operator’s Manual 5

Oxygen Calibration Alarm: An audible and visual Oxygen Calibration
alarm will indicate if an oxygen sensor has failed to calibrate. If this alarm
occurs, remove patient and cycle the power for re-calibration or remove the
driver from service. While the alarm is active, the driver provides CPAP and
FiO2, however, the FiO2may not be accurate. The system calibrates the
oxygen sensor during start up and routinely during operation. There is no
delay for this alarm
Software Fault: An audible and visual Software Fault alarm will indicate
any software fault detected. The system will display a fault code which
should be recorded. If the fault is non-fatal, the alarm can be cleared and
the system will return to normal operation. If the fault is fatal, the driver will
need to have the power cycled or be removed from service. There is no
delay for this alarm
Flow / Pressure Sensor: A visual Sensor Calibration Fault will indicate if a
sensor has failed the calibration during the start up routine. A failure screen
will appear indicating what sensor has failed and informing the user to
remove the device from service.
